SPL Auditor

The Auditor is our interpretation of a high-end headphone amplifier. We strictly followed a purist approach to achieve the highest sound quality.

The basis for such high-end developments is our proved 120 volts reference technology. Core elements are the handmade SPL SUPRA op-amps running on 120 volts – it corresponds to approximately twice that of most modern analog audio semiconductor technologies. Through such 120 volts circuitry and processing we reach performance levels far beyond conventional designs in dynamic range and distortion levels, and such technical specifications exceed all known analog or digital standards.
